SaaS Metrics Dashboard Calculator
See your most important SaaS metrics in one view. Enter your customer count, ARPU, monthly churn, CAC, gross margin and expansion rate, and read off MRR, ARR, LTV, LTV to CAC, CAC payback, NRR, quick ratio and average customer lifetime.
How to calculate your SaaS metrics
- Enter your paying customers and average monthly revenue per user (ARPU).
- Add your monthly churn rate, CAC, gross margin and any monthly expansion rate.
- Read the dashboard of MRR, ARR, LTV, LTV to CAC, CAC payback, NRR and quick ratio, with health hints.
Examples
100 customers at $100/month, 5% churn, $400 CAC
customers = 100, ARPU = 100, churn = 5%, CAC = 400, margin = 80%
MRR $10,000, ARR $120,000, LTV $1,600, LTV:CAC 4.0, CAC payback 5 mo
Adding expansion revenue
monthly expansion = 8%, monthly churn = 5%
NRR 103% (above 100%, so revenue grows even without new customers)
Frequently asked questions
Which SaaS metrics does this calculate?
It computes MRR and ARR, churned MRR per month, customer LTV, the LTV to CAC ratio, CAC payback in months, net revenue retention (NRR), the SaaS quick ratio and average customer lifetime in months, all from one set of inputs.
How are the metrics calculated?
MRR is customers times ARPU and ARR is MRR times 12. Average lifetime is 1 divided by monthly churn, and LTV is ARPU times gross margin divided by monthly churn. LTV to CAC is LTV divided by CAC, and CAC payback is CAC divided by monthly gross profit per customer. NRR is 1 plus expansion minus churn, shown as a percent.
What is a healthy LTV to CAC ratio?
A common benchmark is about 3 to 1 or higher. Below 1 means you lose money on each customer, around 3 is considered healthy, and very high ratios can suggest you are underinvesting in growth. CAC payback under 12 months is also a widely used target.
How should I enter churn, margin and expansion?
Enter them as percentages in the fields (for example 5 for 5% monthly churn or 80 for an 80% gross margin). The tool converts them to decimals internally. Churn must be above 0 and below 100 percent so that average lifetime stays finite.
How is the quick ratio defined here?
The SaaS quick ratio compares revenue gained to revenue lost. With only rates as input, this tool simplifies it to (1 plus monthly expansion) divided by monthly churn on a unit revenue base. Higher is better, and a quick ratio above 4 is generally considered strong.
Is my data private?
Yes. Every calculation runs entirely in your browser. Your customer counts, revenue, churn and CAC figures are never uploaded, stored or shared.
